无法在 spark 中编写 XML

如何解决无法在 spark 中编写 XML

使用下面的代码和下面的 sbt，我尝试在 spark 中从数据帧写入 XML，但出现以下错误

线程“main”中的异常 java.lang.classNotFoundException：无法找到数据源：com.databricks.spark.xml。请在 http://spark.apache.org/third-party-projects.html

找到包裹

import org.apache.spark.{SparkConf,SparkContext};
import org.apache.spark.sql.functions._
import org.apache.spark.sql.SparkSession
import com.databricks.spark.xml
object nestedutil_json 
{
def main(args: Array[String])=
{
val spk1 = SparkSession.builder().appName("Spark sql basics").getorCreate()
import spk1.implicits._
val df_read_json = spk1.read.schema(dataSchemanstd).json("/user/pic1/dataframe_nested_amount1.json")
df_read_json.printSchema
df_read_json.write.format("com.databricks.spark.xml").option("roottag","OfficeInfo").save("/user/pic1/xml/dataframe_nested.xml")
}
}
